“Water?”Here!

SolventMineral

Why it’s here: Serves as the solvent base that dissolves or disperses other ingredients, forming the foundation of most creams, lotions, shampoos, and gels.

Plain water, almost always the largest ingredient by weight in a formula and typically purified or deionized before use.

What the evidence says

We haven’t found a source for this one that you can open and check, so we’re not summarizing the evidence.

Look it up yourself — starting points, not our findings: PubChem · PubMed

Context

Present in nearly all rinse-off and leave-on products; its listing high on an ingredient list simply reflects that it makes up most of the product's weight, not a formulation choice worth scrutinizing.

“Stearyl Alcohol?”Here!

EmollientThickenerEmulsifierVaries by source

Why it’s here: It thickens formulas, helps stabilize emulsions, and contributes to the thick, rich feel of many creams and conditioners. It is frequently paired with cetyl alcohol because the two work well together to build texture.

Another fatty alcohol, closely related to cetyl alcohol but with a slightly longer carbon chain. It is typically derived from vegetable oils like palm or soy, or from animal tallow, then refined into a white waxy solid.

What the evidence says

The Cosmetic Ingredient Review panel has found stearyl alcohol safe as used in cosmetics. Reports of irritation or allergy are uncommon and generally occur only in people with pre-existing skin conditions or very high, repeated exposure in medical contexts (e.g., wound dressings), not typical cosmetic use.

Context

Common in rinse-off conditioners and leave-on lotions alike, usually at low single-digit percentages. Its long history of use across product types has not turned up a concentration-dependent hazard at cosmetic levels.

“Cetyl Alcohol?”Here!

EmollientThickenerEmulsifierVaries by source

Why it’s here: Formulators use it to thicken lotions and creams, stabilize emulsions so oil and water stay mixed, and give a product a smoother, less greasy feel on skin. It is a workhorse texture ingredient in a huge range of moisturizers and conditioners.

A waxy, white solid made of long fatty-alcohol chains, most often derived from coconut or palm oil (or made synthetically from petroleum feedstocks). Despite the name, it has none of the drying, antiseptic qualities of drinking alcohol — it behaves more like a soft wax.

What the evidence says

The Cosmetic Ingredient Review panel has assessed cetyl alcohol as safe for use in cosmetics. It is a very low-level irritant and only rarely causes contact allergy, mostly in people with already-compromised skin who are exposed to many products.

Context

Used in both rinse-off and leave-on products at concentrations typically well under 10%. Its safety profile does not meaningfully change with exposure route because it is not readily absorbed and is not reactive on skin.

“STEARAMIDOPROPYL DIMETHYLAMINE?”Here!

Conditioning agentEmulsifierSynthetic

Why it’s here: Functions as a conditioning agent and mild emulsifier, especially in conditioners and leave-in hair products, where it helps detangle and smooth hair and reduce static.

A fatty amine derived from stearic acid, a common conditioning ingredient built for hair care formulas.

Context

Used at low percentages, generally under 3 percent, in hair conditioners and styling products. Its salt forms neutralize the amine, which is standard formulation practice to keep pH and irritation potential in check.

“Persea Gratissima Oil?”Here!avocado oil

Conditioning agentPlant

Why it’s here: Used as an emollient to soften and smooth skin, and as a moisturizing base ingredient in creams, balms, and hair products.

An oil pressed from the pulp of avocados, rich in oleic acid and other fatty acids similar to those found in skin's own oils.

What the evidence says

We haven’t found a source for this one that you can open and check, so we’re not summarizing the evidence.

“Glutamic Acid?”Here!

HumectantConditioning agentpH adjusterVaries by source

Why it’s here: Used as a humectant and skin-conditioning agent, and sometimes as a mild pH adjuster. It can also serve as a building block for surfactants like sodium cocoyl glutamate.

An amino acid, one of the basic building blocks of proteins, that also occurs naturally in skin as part of its moisture-holding system.

What the evidence says

The CIR Expert Panel reviewed α-amino acids, including glutamic acid, as used in cosmetics, focusing on dermal irritation and sensitization data, and concluded they were safe as cosmetic ingredients at the concentrations and practices of use reviewed. The underlying data are not detailed in the abstract beyond this conclusion, but the safety determination directly covers cosmetic/topical exposure rather than dietary or occupational exposure.

Context

Used at low concentrations in both rinse-off and leave-on products. No meaningful difference in concern between the two contexts at typical use levels.

“Fragrance?”Here!perfume, parfum

FragranceVaries by source

What “Fragrance” can hold

“Fragrance” — also written “Parfum” or “Aroma” — is one word standing in for a scent blend that can be dozens of separate ingredients. It is the one term the rules let a maker leave otherwise undisclosed, to protect the formula, so this single word is as far inside it as the label goes.

The rules do force some of it out: certain fragrance ingredients known to cause allergic reactions must be named on their own once they pass a set amount. When they are, you will see them listed separately — and we mark them.

That named-allergen list is growing — EU rules expanded it from 26 substances to about 80, phasing onto labels through 2028. Roll Call marks the long-established set for now, with more being added. So a label with nothing marked is not a promise there are none; it means none from the set we mark are separately listed.

“BIS-AMINOPROPYL DIMETHICONE?”Here!

Conditioning agentSynthetic

Why it’s here: Provides slip, softness, and shine to hair, and helps reduce breakage during combing by coating the hair shaft.

A silicone polymer modified with amino groups, part of the broader family of amodimethicones used in hair care.

What the evidence says

We haven’t found a source for this one that you can open and check, so we’re not summarizing the evidence.

Look it up yourself — starting points, not our findings: PubChem · PubMed

Context

Used in rinse-off and leave-on hair products alike, typically at low percentages. Silicones of this kind sit on the hair surface rather than penetrating skin, which limits systemic exposure concerns.

“Benzyl Alcohol?”Here!

PreservativeFragranceSolventVaries by sourceEU-disclosed fragrance allergen

Why it’s here: Works as a preservative to prevent microbial growth, and also as a fragrance ingredient and solvent that helps other ingredients dissolve.

A simple aromatic alcohol found naturally in fruits like apricots and cranberries, and in essential oils such as jasmine and ylang-ylang. It is also produced synthetically for cosmetic use.

What the evidence says

The CIR and the EU's SCCS have both reviewed benzyl alcohol and consider it safe at the concentrations used in cosmetics, generally up to about 1 percent as a preservative. It can cause contact allergy in a small subset of people, which is why it appears on the EU's list of fragrance allergens requiring disclosure when present above a threshold.

Context

Concentration matters: preservative use is typically well below levels associated with irritation. Leave-on products carry a slightly higher chance of triggering sensitivity in already-allergic individuals than rinse-off products, simply due to longer skin contact.

10 of 11

“Citric Acid?”Here!the acid in citrus fruit

pH adjusterChelating agentExfoliantVaries by source

Why it’s here: Mainly used to adjust pH, bringing a formula down to a target acidity so it feels right on skin and hair and so other ingredients — some preservatives and thickeners in particular — perform as intended. It also shows up as a mild exfoliant at higher concentrations, and as a chelating agent that binds trace metals to keep a formula stable.

An organic acid found naturally in lemons, limes, and other citrus fruit, though the version in most products is made by fermenting sugar with a mold, Aspergillus niger, rather than squeezed from fruit. It is a fine white crystalline powder that dissolves readily in water.

What the evidence says

Citric acid has a long history of use in food and cosmetics and is reviewed by the Cosmetic Ingredient Review, which found it safe as used. It can be irritating to broken or very sensitive skin at higher concentrations, which is a known and expected effect of most acids rather than a special hazard of this one.

Context

At the low levels used for pH adjustment, effects on skin are negligible. At the higher concentrations sometimes used for exfoliation, mild stinging or redness is possible, especially on sensitive skin, and sun sensitivity can increase slightly with regular use of acid exfoliants — sunscreen is the standard advice alongside them.

“EDTA?”Here!edetate

Chelating agentSynthetic

Why it’s here: Formulators add it in small amounts to bind trace metals that would otherwise degrade the product, dull fragrance, cause discoloration, or interfere with preservatives. It also helps preservatives work better by tying up metals that some bacteria use to build protective films.

A small synthetic molecule, usually used as a salt such as disodium or tetrasodium EDTA, that grabs onto metal ions like calcium, magnesium, and iron and holds them in a stable ring.

What the evidence says

EDTA has been reviewed extensively by the Cosmetic Ingredient Review and the EU's Scientific Committee on Consumer Safety, both of which consider it safe at the low concentrations typically used in cosmetics, generally well under 2 percent. It is poorly absorbed through intact skin. Environmental persistence has drawn separate scrutiny, since EDTA breaks down slowly in water systems, but that concern is about ecology and wastewater, not personal safety.

Context

At the small fractions of a percent used in shampoos, lotions, and cleansers, it functions purely as a behind-the-scenes stabilizer rather than an active ingredient the skin is meant to respond to. Rinse-off or leave-on makes little difference here given how little is used and how little penetrates skin.
